If Seth traveled 1 mile in 57.1 seconds. About how fast does Seth travel in miles per hour?

irga5000 [103]

Answer: Seth is travelling at 63.047mi/hr

Step-by-step explanation: First convert 57.1 seconds to hours.

1 hour is equal to 3600s so multiply 57.1sec by 1hr/3600s to get 0.0158 hr

The formula for speed distance over time. v=d/t

v= 1mi/0.0158hr

v= 63.047mi/hr

7. Tyson obtained a loan from the bank at 7.5% simple interest for 2. 5 years. If the simple interest was

9966 [12]

Answer:

7.He borrowed $1853.33

8.She received $28990.936

Step-by-step explanation:

7.Let x be the amount borrowed by Tyson

Rate of interest = 7.5%

Time = 2.5 years

Simple Interest = 347.50

Formula : $Si = \frac{P \times T \times R}{100}$

Where SI = simple interest

P = Principal

T = Time

R = Rate of interest

Substitute the values in the formula :

$347.50=\frac{x \times 2.5 \times 7.5}{100}\\\frac{347.50 \times 100}{2.5 \times 7.5}=x\\1853.33=x$

Hence he borrowed $1853.33

8) Principal = 20000

Rate of interest = 9.5%

No. of compounds per year = 2

Time = 4 years

Formula : $A=P(1+\frac{r}{n})z^{nt}$

Where A= amount

r = Rate of interest

n = no. of compounds

t = time

Substitute the values in the formula :

So, $A=20000(1+\frac{9.5}{200})^{2(4)}$

A=28990.936

Hence she received $28990.936

A turkey cost $1.05 per pound. There are going to be 15 people at the Thanksgiving dinner. Plan for each person to eat two, 3/8

lina2011 [118]

Answer:

It will take 135 minutes or 2 hours and 15 minutes

Step-by-step explanation:

What we need here is to get the total

amount in pounds of turkey to be cooked

each person eats 3/8 pound servings

Total pound per person would be 3/8 * 2 = 3/4 pound servings

From what we have, there are 15 people at the dinner,

The total pounds to cook will be

15 * 3/4 = 45/4 pounds

Per pound of turkey, it takes 12 minutes

For 45/4 pounds, it will take

45/4 * 12 = 135 minutes

Let us convert this to hours

That will be 2 hours and 15 minutes

Which two angles in the figure are obtuse angles?

ValentinkaMS [17]

Answer: C. ∠SQP and ∠TQR

Step-by-step explanation:

Since, by the given diagram,

m∠TQR = m∠SQP (vertical angles)

And, m∠TQP < m∠TQR

By adding ∠TQR on both sides,

m∠TQP + m∠TQR < m∠TQR+m∠TQR

⇒m∠TQP + m∠TQR < 2 ∠TQR

⇒ 180° < 2 m∠TQR ( Because ∠TQP and ∠TQR are linear angles)

⇒ 90° < m∠TQR

Hence ∠TQR is a obtuse angle,

⇒ ∠SQP also is a obtuse angle.
